SLUICEL Specification of Letters Patent.

Patented May .13, 1919.

Application filed. February 24, 1917. Serial No. 150,789.

To all whom it may concern:

Be it known that I, CELEsTIN GUILMART, a citizen of the United States, residin at Goshen, in the county of Litchfield and tate of Connecticut, have invented certain new and useful Improvements in Sluices, which the following is a specification.

This invention relates to sluices, and more particularly to a sluice or drain for roads.-

One of-the main objects of the invention is to provide a sluice of simple construction and operation which is adapted to beplaced in a road so as to prevent washing of the same. A further object is to provide asluice so constructed as to direct the water from the crown of the road into the gutter, and adapted to be quickly and easily secured in the proper position in the road. A further object is to provide a sluice which can be produced at relatively small cost. Further objects will appear from the detailed description.

In the drawings: 7

the grating removed,

Fig. A is a section on line H of Fig. 1,

Fig. 5 is a fragmentary detail sectional view of the bracket for securing the sluice in position.

The sluice is provided with a central longitudinally extending trough 1 mounted between the two horizontal side plates 2 and 2. The plates 2 and 2 and trough 1 are transversely extending sup- 3, 4, and 5. The plate 2 is provided with a plurality of spaced transversely extending arcuate grooves 6 which communicate at their inner ends with the trough 1. Certain of these grooves, as 6*, are cut away at their inner ends to provide semi-elliptical openings 7 extending through the side of trough 1.

In using my sluice, road with the upper ing slightly beyond the wheel track, and is directed downwardly from the crest or crown of the road toward the gutter. The water which normally collects in the wheel track flows over the plates 2 and 2 into the central trough 1 down which it flows into the gutter. The plate 2 will be placed toward the higher point of the road, in the case of a road on a hill or incline, S0 that the supported by porting beams it is secured in the sition, an angle or broader end extendgrooves 6 and 6 will provide meanswhereby the drainage can easily enter the central trough 1. The openings 7 provide a series of traps which will receive and retain heavier. articles, such as pebblesand small stones, which might tend to stop the trough 1 and thus interfere with the proper flow of drainage through the same. As will be noted, when the sluice is in operative position, the grooves 6 with which theopenings 7 communicate will be positioned closely adjacent the wheel track where the greater numberof heavier articles such as pebbles and thelike will be most apt to be knocked or washed into the sluice.

For securing the sluice inoperative po bracket 8 has one arm 8 provided with a vertically extending slot .9 through which is passed a bolt 10 secured in the supporting beam 5 of the sluice ad'- jacent one corner thereof. The other arm 8 of the angle bracket 8 is adapted to be secured by a screw bolt 11 to a block or stone 12 which is set in the road a suitable distance below the surface of the same. The arm 8 of the angle bracket is provided, contiguous with the arm 8", with a transversely extending groove which receives an adjust ing block or strip 13. This strip is adapted to engage the underface of the bolt 10 and serves to adjust the sluice relatively to the block 12, thus providing means whereby, by providing strips of different widths, the inclination of the sluice can be varied. The sluice is set in the road so as to bring its upper surface approximately flush with the upper surface of the road.

A suitable shaped relatively heavy grating 14: is provided with downwardly extending side pieces 15 which fit snugly about the plates 2 and 2. This grating serves to protect the sluice proper from injury due to vehicles passing over thesame, without in any way interfering with the flow of drainage to and through the sluice.

What I claim is:

1.. A sluice comprising spaced side portions, and having a series of transverse parallel depressions, a trough common to said depressions at the inner ends of the latter, and a grating over said trough and supported by the sides.

2. A sluice comprising spaced sides, one of said sides being longer than the other, a tapered trough supported by said sides and having a plain portion and a series of trans- I spaced tables,

verse parallel grooves in its opposite portion, a central longitudinal depression with Which the inner ends of the grooves communicate, certain of said grooves inclining toward the trough and having openings communicating therethrough, and a grating over the trough.

3. In a sluice, the combination of two spaced tables, and a longitudinally extending trough mounted between provided with a plurality of spaced transversely extending grooves communicating with the trough,and said trough being provided with a plurality of spaced openings through one side communicating with certain of said grooves. V

4:. Ina sluice, the combination of two a longitudinally extending trough mounted between thetables, one of said tables being provided in its upper face with plurality of spaced transversely extending grooves communicating with the qopies of this .patent may be. obtained for five cents each, by addressing the the tables and open at one end, one of said: tables being trough, and means carried by the sluice for securing the same in operative position at an inclination and for adjusting the inclination of the sluice.

5. A sluice comprising spaced sides, one of said sides being longe than the other, a

tapered trough supported by said sides and havinga plain portion and a series oftransverse parallel grooves in its opposite portion, a, central longitudinal trough with which the inner ends of: the grooves communicate, certain of said grooves inclining toward the trough and having openings communicating therethrough, a grating over the trough, means for bracing the center of the trough and means for ad usting the inclination of the sluice.

In testimony whereof I aifix my signature presence of two witnesses.
